Globally, there is an ever increasing need for renewable energies within the energy mix to limit global warming due to greenhouse gas emissions. Offshore wind is now a main source of renewable energy.
Floating wind will allow to fully exploit this potential, with important development opportunities.
Increased competitiveness over time compared to bottom-fixed wind
There is a high potential of cost reduction over time. Indeeed the Levelized Cost of Energy (LCOE) will benefit from :
Is it estimated that about 5% of offshore production is consumed for offshore electric power generation, resulting in :
Thanks to TrussFloat‘s superior stability and high deck capacity, floating wind power can be used for direct water injection in mature O&G reservoirs. This innovative technology reduces scope 1 and 2 emissions, prolongates reservoir lifetime and allows important savings in capital expenditure in situations where the injection well is far away from the production platform. TrussFloatTM floating platform accomodates and powers all necessary equipment such as sea water lift pump, water treatment plant, booster and water injection pumps. The whole system has to be designed such that the average water injection over a certian period of time meets the O&G production requirements. In this case, the reservoir serves as natural potential energy storage system to counter the intermittency of wind power.
Floating wind power can be used to produce green hydrogen offshore. This award winning concept accompanies O&G majors towards a carbon neutral world by giving their O&G infrastructure a second life.
We believe that this should happen in two phases:
Phase 1: Electrification of O&G platforms or direct water injection with floating wind turbines. This is particularly interesting for mature fields with a lack of associated gas for thermal power production.
Phase 2: Installation of hydrogen production equipment on the floating wind turbines and hydrogen injection into existing O&G infrastructure. This is particularly interesting for near CoP O&G fields.
Phases 1 and 2 can also be carried out in parallel, depending on the maturity of the O&G production field.
After a two-stage application process, Dolfines has been laureate of the Marine Energy Alliance (MEA) for this concept. Dolfines is collaborating closely with MEA partners in the technical and commercial development comprising the basis design for open sea testing prototype including permitting aspects, hydrogen export line and mooring system, levelized cost of energy optimization and business case development.
Thanks to TrussFloat‘s superior stability at light weight, floating wind power can be used to power compressors to inject captured CO2 in mature or depleted reservoirs far off the coasts and in deep water.
In case of mature reservoirs, CO2 injection enhances production. The whole system has to be designed such that the average CO2 injection over a certian period of time meets the O&G production requirements. In this case, the reservoir serves as natural potential energy storage system to counter the intermittency of wind power.
In case of depleted reservoirs, the carbon dioxyde can be transported offshore using existing pipelines. This innovative technology reduces scope 1 and 2 emissions for carbon capture and storage (CCS) and allows important savings in capital expenditure in situations where the existing offshore O&G infrastructure can be used.
